Immunohistochemistry (IHC) results showing protein levels of autophagy-associated genes in LUAD and normal tissues, a IHC results of ITGB4 in LUAD (staining: high; intensity: strong; quantity: 75–25%; location: cytoplasmic/membranous) and in normal tissue (staining: low; intensity: weak; quantity: 75–25%; location: cytoplasmic/membranous). b IHC results of CDKN2A in LUAD (staining: high; intensity: strong; quantity: > 75%; location: cytoplasmic/membranous/nuclear) and in normal tissue (staining: low; intensity: moderate; quantity: < 25%; location: cytoplasmic/membranous). c IHC results of ERO1A in LUAD (staining: high; intensity: strong; quantity: 75–25%; location: cytoplasmic/membranous) and in normal tissue (staining: not detected; intensity: negative; quantity: none; location: N/A). d IHC results of NLRC4 in LUAD (staining: not detected; intensity: negative; quantity: none; location: N/A) and in normal tissue (staining: low; intensity: moderate; quantity: < 25%; location: cytoplasmic/membranous)
